Description
The ITP Straight Styli – Type T with a ruby ball is a precision probing stylus designed for high-accuracy measurements on small parts and delicate surfaces. Ideal for engineers using clamp holders, this no-thread design combines flexibility with durable materials to deliver reliable, repeatable data.
- Stem material: Tungsten carbide for stable rigidity and long wear life in repetitive probing tasks.
- Tip option: Ruby ball available in sizes Ø0.2 mm to Ø5.0 mm to suit both fine-detail work and broader contact areas.
- Overall length: 15.25 mm, providing a compact profile for tight measurement envelopes.
- Thread: Without thread, enabling flexible mounting and easy integration with compatible clamp holders.
- Configuration: Straight shaft that can be supplied in single- or multi-stepped configurations to match probing needs.
- Compatibility: Designed to work with the appropriate clamp holders for secure, repeatable setup.
- Custom sizes: Other ruby ball diameters can be requested via the configurator or by e-mail.
This stylus is engineered to deliver dependable contact with minimal deflection, supporting precise data capture in applications such as coordinate measuring (CMM), surface mapping, and inspection of small components. The ruby ball reduces wear and provides a consistent contact radius, while the tungsten carbide stem maintains performance across numerous cycles. Whether you’re verifying tight tolerances on micro-mechanics or performing detailed quality checks on assembly parts, this stylus offers the right balance of flexibility, durability, and accuracy. The absence of threads reduces alignment constraints, making it easier to achieve repeatable measurements with your chosen clamp system.
